Description
Technical Field
The invention discloses a welding wire position adjusting mechanism for deep and narrow weld joint welding, relates to the technical field of welding, and particularly relates to a welding wire position adjusting mechanism for deep and narrow weld joint tungsten electrode argon arc welding.
Background
In TIG welding, especially assembly welding, the distance between the welding wire and the tip of the tungsten electrode, the included angle between the welding wire and the tungsten electrode, and the stability of the welding wire position directly affect the welding quality. However, in the deep and narrow weld joint welding with limited top space, the existing welding wire position adjusting mechanism can not enter a groove or can not realize the accurate adjustment of the welding wire position; this directly affects the quality of the weld.
Aiming at the problems in the prior art, a novel welding wire position adjusting mechanism for welding deep and narrow welding seams is researched and designed, so that the problems in the prior art are very necessary to be overcome.
Disclosure of Invention
According to the technical problem that the welding wire position adjusting mechanism cannot ensure the welding quality due to the fact that the welding wire position adjusting mechanism cannot enter a groove or cannot realize accurate welding wire position adjustment when a deep and narrow welding seam with limited top space is welded in the prior art, the welding wire position adjusting mechanism for welding the deep and narrow welding seam is provided. The invention mainly utilizes the welding wire position adjusting structure capable of adjusting the angle, the direction and the extending length to adjust the position relation between the welding wire and the tungsten electrode, thereby achieving the purposes of meeting the requirements that the welding wire smoothly enters the crevasse and meeting the requirements of deep and narrow weld joint welding.
The invention designs a mechanism which can enter a deep and narrow groove of a closed space and can accurately adjust the position of a welding wire, and the mechanism has an exquisite and compact structure.

furthermore, the screw adjusting structure and the rear hinge seat are respectively clamped and arranged at the front part and the rear part of the welding gun through welding gun clasps;
furthermore, the screw adjusting structure and the bottom of the rear hinge seat are respectively provided with a wire feeding pipe fixing block;
further, the front and the back of the wire feeding pipe respectively penetrate through the two wire feeding pipe fixing blocks and are fixed in position through the fastening screws on the wire feeding pipe fixing blocks;
furthermore, the welding wire is arranged in the wire feeding pipe, the welding wire extends out of a wire feeding nozzle at the front part of the wire feeding pipe, and the front end of the welding wire is positioned at the lower part of a tungsten electrode of the welding gun.
Further, the screw adjustment structure includes: the left-handed screw seat, the adjusting screw and the right-handed screw hinge;
further, the left-handed screw seat is fixedly arranged at the bottom of the welding gun holding clamp through a bolt;
furthermore, the right-handed screw rod hinge is hinged with the wire feeding pipe fixing block;
furthermore, the upper end and the lower end of the adjusting screw rod are respectively provided with a left-handed internal thread and a right-handed internal thread, and are in threaded connection with the left-handed screw rod seat and the right-handed screw rod through the left-handed internal thread and the right-handed internal thread to form a complete screw rod adjusting structure.
Furthermore, the length of the external thread of the left-handed screw on the left-handed screw seat is the same as that of the external thread of the right-handed screw on the right-handed screw hinge.
Further, the left-hand internal thread depth is the same as the right-hand internal thread depth.
Furthermore, the adjusting screw rod is of a replaceable structure, and the adjusting screw rod with a proper length is replaced according to different groove depths.
Further, the rear hinge seat is fixedly arranged at the bottom of the welding gun holding clamp through a screw; and is connected with the wire feeding pipe fixing block through a hinge pair.
The use mode of the invention is as follows:
1. the front and rear positions of the wire feeding pipe can be adjusted by loosening the set screws on the front and rear wire feeding pipe fixing seats, so that the distance between the wire feeding nozzle and the tungsten electrode is adjusted, and the set screws are screwed down after the adjustment is finished to fix the position of the wire feeding nozzle;
2. after clamping screws held by the front welding gun and the rear welding gun are loosened, the whole welding wire adjusting mechanism can rotate around the axis of the welding gun, so that the left-right distance between the welding wire and the tungsten pole tip is adjusted, and the clamping screws are screwed to fix the left-right position of the welding wire after the adjustment is finished;
3. the adjusting screw rod is rotated to adjust the matching depth of threads at two ends of the adjusting screw rod, so that the vertical distance between the welding wire and the tungsten electrode is accurately adjusted;
4. due to the fact that the adjusting range of the screw is limited, when the depths of welding seams are different, the welding wire cannot be adjusted to a proper position by the adjusting limit of the existing adjusting screw, and the adjusting screw with a proper length can be replaced;
5. in general, the distance between a wire feeding nozzle and a tungsten electrode and the left-right distance between a welding wire and the tungsten electrode do not need to be frequently adjusted, and the up-down distance between the welding wire and the tungsten electrode needs to be frequently adjusted; the vertical distance is adjusted through the screw rod, the adjustment is accurate and high, and the device is convenient and practical.
Compared with the prior art, the invention has the following advantages:
1. according to the welding wire position adjusting mechanism for welding the deep and narrow welding seams, the position of the wire feeding pipe can be adjusted by adjusting the set screw on the wire feeding pipe fixing seat, so that the distance between the wire feeding nozzle and a tungsten electrode is realized, namely the distance between the front end of a welding wire and the tungsten electrode is realized;
2. according to the welding wire position adjusting mechanism for welding the deep and narrow welding seams, the welding gun is adjusted to clamp on the welding gun to rotate axially, and the left and right distances between a welding wire and the tip of a tungsten electrode are adjusted;
3. according to the welding wire position adjusting mechanism for welding the deep and narrow welding seams, the up-down distance between the welding wire and the tungsten electrode can be adjusted by adjusting the screw rod adjusting structure;
